Focus Deadlock issue was created by mikeE

I'm getting focus failures tonight with a deadlock occuring and I don't know why. Attached is a snippet of the log. I'm not sure where the position of 12317 for a IN and OUT limit comes from. It's the same number throughout the night. I'm guessing the focuser is trying to move to 12313 which is outside the IN and OUT limits causing the deadlock. I'm using Gradient and Iterative (like always) with an initial step size of 20, max step size of 40 and max travel at 500. Running kstars 3.5.0 final. any ideas?

This kind of deadlock happens when the focus cannot get reliable and consistent results for HFR. Could be bad sky conditions?
